1. Raw and Cooked Feeding In rural areas, many pig farmers have a habit of feeding cooked foods. It is believed that cooked feeds can reduce the volume of feed, soften crude fiber, allow pigs to eat more, and increase digestibility. According to experiments, the type of feed is different. Raw and cooked feeds are different. Green and coarse feeds are fed better than raw feeds. The digestibility of dry matter and carbohydrates is also higher in the clinker group, protein and crude fiber. There was no significant difference in digestibility. In the concentrate type diet, the bean seed is actually cooked and fed better than the raw one. However, in most concentrate type diets, raw and feed feeds are better than cooked feeds. Normally cooked concentrates lose 5% to 10% of nutrients. Raw foods are fed to pigs, and the average daily weight gain is 10% higher than that of cooked feeds. For each kilogram increase in gross weight, 0.2 to 0.3 kilograms of refined material can be saved, and there is no difference in dry matter digestibility. Protein digestibility is higher than that of ripening. In addition, feeding raw pigs can save a lot of labor and fuel. However, some toxic or easily contaminated feeds such as rapeseed cakes, cottonseed cakes, glutinous rice, etc. can be detoxified or disinfected after cooking. 2. Thick feeds and thin feeds Thin feeds due to high water content, dilute soups, causing decreased secretion of digestive juices, accelerating gastric emptying, shortening the time the feed stays in the stomach, and tends to reduce the digestibility of feed nutrients. Thick-feeding, in particular, raw-dry feeding and raw-wet feeding, can enhance the masticatory function of the pigs, promote the secretion of digestive juices, prolong the stay of the feed in the stomach, and increase the digestibility of nutrients. Therefore, it is recommended to use thick feed, dry feed, or water. The degree of dryness and wetness of the dry feed mixed with green feed slurry should be taken as close as possible and scattered. 3. Small and large meals must be based on the type of pig, age, season and feed properties to determine the number of meals, can not be generalized. The suckling piglets have small stomach volume and weak digestion. From the 7th day of age, they are mainly lure-feeding, which can be limited to the number of meals; from 20 days of age until weaning, they can feed more than 6 tons per day; pigs that have just weaned digest feed The function is in an increasingly enhanced stage and can be fed 4 to 5 tons per day; sows with gilts and sows in late gestation need more nutrients and can feed 4 tons per day; shelf pigs, big pigs, empty sows, boars Feed 3 meals a day. In summer, the weather is hot, the nights are short, and the pigs are active for a long time. You can add 1 to 2 dilute meals as appropriate to prevent hunger and replenishment. If the winter is cold and the nights are long, the first meal in the morning will be fed early and the evening meal will be fed late to properly open the interval. And in the evening, you have to feed it thick to prevent it from being cold. 4. Timing. Feeding pigs should never be delayed today, but feed them early tomorrow. Feeding pigs should be fixed daily. This will make pigs grow habits. They want to eat as soon as time passes, and they regularly secrete digestive juices. They are particularly fragrant when eaten. They are also easy to digest and are not susceptible to gastrointestinal problems. If the feeding time is not fixed, they disrupt the regularity of the pig’s life. , It is easy to cause digestive disorders, each meal is not fragrant, indigestion, leading to pigs suffering from gastro-intestinal diseases, over time, the pig will be thin, growth retardation. 5. Quantitative. Feeding pigs with a meal of hunger and a full meal will also make the pigs indigestion and slow weight gain. Therefore, after ascertaining the approximate feed intake of pigs, a general feeding amount should be determined. However, the food intake of the same group or even the same pig is often different due to climatic conditions, feed palatability, and feeding techniques. After the feeder has mastered the food intake of the pig, he/she needs to have a flexible grasp of the feed intake based on the nutritional status, feed conditions, and appetite of the pig. Generally, no food is left in the trough after feeding, and pigs are not suitable for troughing. If there is food left in the tank, the next time you can reduce the point; if you do not eat enough, you can feed more in the next time. The appetite of pigs is generally the most prosperous in the evening, followed by morning, and the worst in the afternoon. The amount of feed for one day should be allocated according to this rule, so that the pig always maintains a strong appetite. The feed of the quailized pigs is best fed to a regular feed mill. The formulated feed is formulated according to the feeding standards of pigs of different types of growth and development stages. If farmhouses are self-provisioned, the digestion energy level and protein level of the mixture should also be roughly determined according to the feeding standards. The variety and ratio of each ingredient should not change too much. Fixed temperature food temperature also has a greater relationship with pig health and weight gain. Spring, summer and autumn are generally fed at room temperature. In winter, hot water should be used to prepare feed and warm water. If the food temperature is too low, the pig must consume a lot of body heat to consume a lot of body heat in order to raise the feed to the same level as the body temperature. The body heat must be supplemented by the heat energy generated by the oxidation of nutrients in the feed, which is virtually wasteful. Many feeds may also cause miscarriage and gastroenteritis in pregnant sows. When healthy pigs eat, they have the habit of catching food. Therefore, when feeding pigs, they should not be fed with hot scalding food, otherwise they may burn the mouth mucous membrane or even the esophagus. Feeding hot food for a long period of time can also cause hair loss and hinder the development of pigs. YT-60 YT-60 Shenzhen Sunshine Technology Co.,Ltd , https://www.yatwin.com
